Could someone please add information on how body part exposure is determined. It seems like something that could have its own dedicated page, but all I can find is vague descriptions of the "[Part] Exposed" flags in the Clothes and Armor pages, and a brief mention on the Wings page that some (but not all) wings can be used as covering (except for when they can't).
To hopefully be helpful here is pretty much everything I've been able to figure out about exposure and coverage:
*I think the "#Visible/#Exposed" bit (under "Personal Statistics" > "Body Exposure Level") refers to Chest, Crotch, Ass, and Everything, meaning true Full Exposure results in 4/4, but even a single Transparent Undergarment blocks the Everything exposure for both Visible and Exposed, resulting in -1/-1 on top of whatever hiding/blocking the piece itself does
*The Omnisuit counts as full coverage (i.e. you can walk around Tavros freely), even with the Fully Exposed tag at full libido. This might be a bug
*Large wings (Avian, Demonic, Dove, Draconic, Frostwyrm, and Gryvain) can be used as Full coverage, but this can be toggled off
*Tails with either the Long or Prehensile flag provide limited coverage, but unlike Wings this can't be toggled off
*The Partial Nudity sections refer to the visibility of the individual "naughty bits" left visible by your clothes
-*Chest encompasses all rows of Breasts, and each individual row is a separate bit
-*Crotch encompasses all genitalia (Penis, Balls, and Vagina), while Ass only has the Anus
-*Partial Nudity Exposure lists the "naughty bits" that are not hidden by clothes or specific parts of anatomy, aa well as how many Long or Prehensile Tails are needed to cover them
-*Partial Nudity Exposure is effectively measured in Tails, as any parts covered by other anatomy are not listed there
-*1 Tail can cover all vaginas, the anus, or 1 row of non-Hyper (more than 100 total size rating and any Nipple type besides Flat (for some reason)) breasts
-*1 Tail can cover all penises as long as they have Fur or Feathers with the Fluffy flag or at least one Penis has the Sheathed Flag and Lust is below 66
-*Without Fluff or Sheath, 1 Tail can cover up to 18" of total penis length as long as none of them are Hyper-sized (length is more than either 75% body height or 50 inches)
-*Balls I'm less certain on, but apparently one Tail can hide roughly 60 total cubic inches of ball, with that total ball space decreasing slightly the more individual balls you have, and having a Fluffy furred scrotum or Uniball gives some sort of multiplier I think...
-*Hyper-sized Breasts and Penises cannot be hidden by tails and effectively override the Partial Nudity system, making it extremely difficult to become "decent" without concealing clothes or Large Wings
--* Hyper Penises can still be hidden by a Genital Slit, and Hyper-sized Breasts apparently don't count and can be covered normally by Hair or Tails as long as they have Flat Nipples
*Partial Nudity Coverage lists "naughty bits" that are being covered by other anatomy pieces
-*Hair with a length of at least 25% of the characters height will cover all rows of Breasts, unless the hair is styled up away from the chest
--*I'm not going to test each hairstyle just to see which ones get me kicked off the station
-*Fluffy Fur can hide the Anus unless it is Fully Pumped or Hyper Pumped
-*A Genital Slit will hide all penises, regardless of size
-*Large Wings wrapped around the body are only listed as covering the Breasts, despite giving Full coverage
*The Partial Nudity system is actually the one that determines whether you're sufficiently clothed; as long as you have the proper anatomy to hide your anatomy, you can go streaking through the Merchant Deck like Lady Godiva with no repercussions
-*Equipment Body Exposure is only used to determine what bits to apply the Partial Nudity to, meaning the 4th "Everything" exposure is actually pointless (at least in this context) since it doesn't have any "naughty bits" associated with it
